Thanks for this, @jchak7, and welcome. I am reviewing as code owner for tests/, so this is about tests/application-answers.test.mjs only.
Nice test. Pinning the reader as a fixed point instead of chasing byte-equality is the right call, and the header at 8-33 says why: inline() collapses label whitespace, valueText() joins arrays with , , and pick() forgets which key spelling was used, so parse(format(x)) === parse(format(parse(format(x)))) is the invariant that actually holds. The anti-vacuity guard at 98-99, which asserts the corpus produced entries before any equality check, is the part I was most glad to see, and the boundary agreement with upsert at 182-206 plus the byte-stable formatter check at 219-233 cover the two ways this could quietly break. I ran it on e9e047f: all seven assertions pass.
One thing, minor, in this file.
The inline Not recorded sentinel is promised but never rendered. The header at 21-23 says the suite pins the four sentinels and that "the two 'Not recorded' spellings must read back as empty." The corpus produces two of the three parser sentinel paths: block - None captured. for an empty group (corpus[1]) and block > Not recorded. for an empty free-text answer (corpus[0].freeText[2]). It never produces the inline spelling. compactLines (application-answers.mjs:74) renders **Label:** Not recorded for a selection or field value that exists with an empty value, fileLines (84) does the same for a file with an empty path, and the parser strips both back to '' at value === NOT_RECORDED_INLINE ? '' and file === NOT_RECORDED_INLINE ? ''. Neither branch is hit by any fixture. Drop either strip in a later refactor and an empty selection round-trips to the literal answer Not recorded, a value nobody typed, with this suite still green; the fixed-point test cannot catch it because no corpus entry renders the inline form. Adding a selection, a field value, and a file entry with empty values to corpus[0] covers it (they survive normalization: list() at application-answers.mjs:32 does not filter, I checked), then assert each reads back as '' rather than Not recorded. It is worth a direct assertion because this is the one sentinel path that fabricates content instead of dropping it, and the header already claims it.

Sorry for the slow first reply, @jchak7. The framing is what makes this worth doing:
A formatter with no parser is a one-way door: everything downstream that needs the data has to re-derive it from prose, and every consumer re-derives it slightly differently. A real parser turns that into a contract with two sides, and the round-trip becomes testable: format → parse → compare. That's the property I'd want asserted rather than "the parser handles these five shapes" — a round-trip test stays honest when the format grows a field, and a shape list goes stale silently. Not merged tonight (per-session merge ceiling), queued. One question worth answering in the PR body: what happens on a section the parser can't read — throw, or return partial? For recovery of the user's own previous answers, a partial parse that silently drops one is worse than a refusal, because the missing answer looks like an answer they never gave. |

Thanks all three. The most useful thing since my last push: a reviewer found that my fix had the same defect the PR is about. Details under the coderabbitai heading. @santifer: silent dropsCurrent behaviour:
It never throws. On your specific worry it behaves as badly as you guessed. A section where one selection line lost its numbering and one file line lost its bold: No throw, no null, no signal. I'd push back on throwing by default, though, not on the substance. Totality is doing real work here: if the parser threw on malformed input, So the fix keeps it total and makes the refusal opt-in: parseApplicationAnswersSection(text) // unchanged, byte for byte
parseApplicationAnswersSection(text, { strict: true }) // throws, naming what it refusedI tried The intended caller is Module cost is +27 / -11: an optional On "default unchanged": I diffed @coderabbitai: my fix had the bug the PR is aboutI threaded the skip callback into Chasing it down turned up a worse case than the reported one. Dropping happens when the orphaned quote lines arrive with no entry open. When a heading in the middle of the block loses its numbering, That's not a dropped answer, it's a corrupted one, and no assertion in the suite could see it before this commit. Section 7c pins both paths: the default still drops and still absorbs (unchanged, on purpose), strict throws on each mangling separately, and the message names the offending heading. @Scott-Emberson: the inline sentinelYou were right, including the part I'd have got wrong on my own: the branches exist and are correct, and nothing executes them. Done as you specified, appended to selections: { question: 'Work authorization', selection: '' },
fieldValues: { question: 'Earliest start date', answer: '' },
files: { field: 'Portfolio', path: '' },plus a Your prediction that the fixed-point test can't catch it: I ran it rather than take it on faith. Deleting either strip: Both mutants die on the new assertion and nothing else, and the fixed point stays green through both, exactly as you said. The general shape, now in the header comment: the property is blind to any sentinel that survives its own re-render. Also confirming your check on I held each new assertion to the bar you set: reverting the fix has to kill that assertion and nothing else. Reverting the free-text skip fails 7c only; 7b and the fixed point stay green. Ten assertions in PR body updated with an "Error handling" section covering the above, and the suite numbers corrected.

Re-reviewed at 72e97205. Our one point from last pass is resolved cleanly. Section 5b now pins the inline Not recorded sentinel in both directions: it asserts the formatter actually emits **Work authorization:** Not recorded, then that each entry strips back to '' on parse. Delete either strip in parseCompactEntries/parseFileEntries and 5b fails, so it is not a fixed-point blind spot any more.
The strict-mode additions are the right kind of test. 7c constructs a free-text section whose heading loses its numbering mid-block, asserts under the default parser that the orphan quote lines get absorbed into the preceding answer (the actual data-corruption class this PR exists to catch), then asserts strict:true throws and names the entry. Every strict assertion keys off strictThrew !== null, so a no-op strict mode would fail all three blocks rather than pass silently. Hermetic, matches the neighbour shape, round-trip fixed point intact. Approving.

What does this PR do?
formatApplicationAnswersSectionhas been write-only since it shipped — nothing in the tree can read a rendered## Application Answerssection back, somodes/apply.mdrecovers previous answers by greppingreports/for a company name and re-reading the prose. This adds the inverse,parseApplicationAnswersSection(reportText), returning the same shapenormalizeApplicationAnswersSnapshotproduces, so a parsed section can be handed straight back to the formatter or merged with a fresh snapshot.Related issue
None. See Routing at the bottom — happy to be redirected if you'd rather this went issue-first.
Type of change
Why here and not a new module
contacts.mjs(parseContacts/contactToVcard) andassessment-log.mjs(parseAssessments/buildRow) both keep reader and writer in the module that owns the format. The parser also needs to invert seven module-private helpers (inline,valueText,pick,quoteBlock,qaLines,compactLines,fileLines) and shareAPPLICATION_ANSWERS_HEADING/VALID_STATES; splitting would mean exporting internals or duplicating them, and duplicated readers drift.The
tracker-parse.mjs/tracker-utils.mjssplit is not a counter-example — that boundary is about side effects (locking, atomic writes), not parse-vs-format. Both functions here are pure.The property this guarantees — and the one it does not
It does not claim byte-equality with the input snapshot, and asserting that would be wrong. The formatter is lossy by design:
inline()collapses whitespace in every labelvalueText()joins arrays with', ', so['a, b','c']and['a','b','c']render identicallypick()discards which of the four accepted key spellings was usedNot recorded/> Not recorded.Answer 1/Selection 1/Field 1/File 1What holds, and what the tests pin, is that one render normalizes and every render after that is stable:
Parsed entries use the primary key the formatter picks first (
question/answer,question/selection,field/path), which is what makes re-rendering a fixed point rather than falling through to fallback labels.Multi-line answers are the one genuinely lossless payload and are asserted as such, including the blank line
quoteBlockrenders as"> ".Error handling
parseApplicationAnswersSectionis total — it never throws, for any input includingnull,undefinedand''.## Application Answersheading →null. The section is absent.Date/Statebecome''; a group that can't be sliced becomes[].Totality is load-bearing for the property this PR asserts: a parser that threw on malformed input would make
parse(format(x))partial, and the fixed-point assertion would hold only on well-formed input — the input that least needs a guarantee.Opt-in refusal (
{ strict: true }), added after @santifer's review. By default a line inside a group that matches no entry pattern is skipped, so a partially-mangled section returns a snapshot indistinguishable from a clean parse — for apply-mode recovery that is worse than a refusal, because the missing answer looks like an answer the user never gave. Worse, an unnumbered heading mid-block leaves the previous entry open, so its quote lines are absorbed into the previous answer rather than dropped — a corrupted answer, not a missing one.strict: truethrows instead, naming every line it could not read.The default path is unchanged, verified rather than asserted:
JSON.stringify(parse(input))is byte-identical between the pre- and post-change module across eight input variants, and formatter output is unchanged. So the fixed point above still holds and no existing caller is affected.Boundaries
parseApplicationAnswersSectionuses the same heading probe (/^## Application Answers\s*$/m) and terminator (/^## .+$/m) asupsertApplicationAnswersSection, so the reader and the writer agree on where the section starts and ends by construction. Returnsnullwhen there is no section.Risk
Additive only. No new file, no new data file, no new mode, no new CLI surface, no new dependency, no change to any existing export.
modes/apply.mdis coupled to this exact rendering and is CI-blind, so the suite includes an explicit assertion that formatter output is unchanged — and the three existing inline assertions intest-all.mjswere re-run against the patched module and still pass.Tests
tests/application-answers.test.mjs, auto-discovered (notest-all.mjsregistration, noSYSTEM_PATHSentry). Ten assertions: fixed point, key spelling, multi-line fidelity, all four sentinels including the inline spelling, section boundary against a report with a following##block, null on absence, opt-in strict refusal across both the compact groups and the free-text group, and formatter-unchanged.Anti-vacuity guard included — a round-trip suite over an empty corpus passes trivially, so the corpus asserts it produced entries before any equality check.
Full suite on this branch: 3703 passed, 0 failed, 1 warning (a Dashboard build skipped for no Go compiler in my environment — not introduced by this change). The three required
testworkflows are still awaiting maintainer approval for a first-time contributor, so treat this as a local run rather than CI.Routing
Reading CONTRIBUTING, this looked borderline on issue-first: it is a new exported function, but adds no new file, data file, mode, CLI surface or dependency, and no behaviour change to any existing caller — question 2 ("who pays the maintenance?") is ~90 lines in a module already maintained. I've sent it directly on that basis. Happy to split it behind an issue if you'd rather route it that way.
